1. Adaptation and plasticity within and across generations
Abstract : The environment is seldom stable but often changes from one state to another and in order to survive and reproduce organisms need to respond to those changes. If the change is fast, genetic adaptations may not evolve quickly enough and organisms must adopt other strategies, such as phenotypic plasticity. READ MORE

2. Condition-dependence in life history evolution
Abstract : Ageing is the progressive physiological deterioration that appears with increasing age and eventually leads to a decline in survival and reproduction. This physiological process is omnipresent across the tree of life, but the expected trajectory can widely vary between and within species. READ MORE

3. Age-specific trade-offs in life-history evolution
Abstract : Trade-offs prevent selection from driving all fitness-enhancing traits towards values that would maximize fitness. Life-history trade-offs, such as the one between survival and reproduction are well-studied, yet trade-offs can also involve behavioural or cognitive traits. READ MORE

4. Experimental Evolution of Life-history : Testing the Evolutionary Theories of Ageing
Abstract : Ageing reduces fitness, but how ageing evolves is still unclear. Evolutionary theory of ageing hinges on the fundamental principal that the force of natural selection declines with age. READ MORE

5. Evolutionary consequences of sex-specific selection
Abstract : Sex-specific selection is widespread, evident by the evolution of sexual dimorphism in many traits in sexually reproducing taxa. The reason why the sexes may experience selection that differs in direction or magnitude is often linked to the reproductive strategies associated with the sex-specific reproductive physiology.
